The Voice UK coaches are to release a music video together to help promote the series, we can reveal.
An onlooker at the recording said: "It was incredible to see such big names in music perform together. Hopefully this has set the bar for the rest of the show.
"Everyone was jumping out of their seats and dancing along. It was really exciting. The whole concept seems to be very different from The X Factor, which will be very refreshing."
The performance of the track will be released in the lead up to the start of the series in March to help build up buzz around the new show.
The Voice UK starts this Spring on BBC One.
